We've had a couple of glitches on this site recently that I wanted to apologize for.

Firstly, the e-mail function, whereby you can get the column sent to your e-mail address, hasn't worked for a few weeks, but is now fixed. Just go to the box to the right, enter your e-mail address, you'll get an e-mail from me, a prompt, and the column will be sent to you twice a week.

Secondly, we've had to end the commentary function on the site, which I regret. I greatly enjoyed reading your comments and your conversations with each other and if that function can be restored, we will do so without delay.

Thanks for your patience.
